Abstract

The present invention relates to an apparatus for detecting toxicity in water using sulfur-oxidizing bacteria, in which air and a water sample are introduced into a reactor containing sulfur-oxidizing bacteria and sulfur particles, and then the amount of sulfuric acid resulted from oxidation of the sulfur particles by the sulfur-oxidizing bacteria is analyzed based on the pH and electrical conductivity (EC) of the water sample, thereby detecting toxicity in the water sample. In the apparatus, the measured values of pH and electrical conductivity (EC) are not affected by air bubbles generated when the air and the water sample are introduced into the reactor, and the activity of the sulfur-oxidizing bacteria is not adversely affected by the pH of the water sample, so that accurate measurement results can be obtained. In addition, the apparatus comprises a plurality of reactors, and thus can continuously perform the detection of toxicity.
